Deccan suffered their second loss on the trot in the tournament with their nine-run defeat against Kolkata Knight Riders here last night and Sangakkara felt that his batsmen lacked the attacking instinct.
"Our batsmen now have to start rethinking and attack slow bowlers," Sangakkara said.
Knight Riders` left-arm spinner Iqbal Abdulla scalped three wickets for 24 runs to play a major role in his side`s win and Sangakkara said his batsmen had paid to much respect on the bowler.
"He (Abdulla) is not a bad bowler and he managed to bowl a couple of good overs at the start. But we need to bat a bit smarter. A few less mistakes would have got us over the line," said the Sri Lankan wicket-keeper batsman.
"They (KKR) batted well to get there. But it was a gettable score if we had a better start. We lost wickets at regular intervals," he said.
Sangakkara conceded that Deccan gave a 15 runs extra but backed pacer Ishant Sharma, who was lacklustre against Knight Riders today.
"We gave away about 15 runs too much. Ishant is bowling well. We have a good pace combination and there is no worry there," he said.
The Deccan skipper said that his team is just one win away from making their presence felt in the tournament.
"As a team we need just one win under our belt," Sangakkara said.
